Your videos are helping me survive O-Chem! Thanks for your videos! I'd be happy to see more on SN1 & SN2 reactions with a more in depth exercise where we have to create the products ourselves. That is a bit more challenging and I would love to see how you explain it! :)
Hi melissa, your videos are really helpful and easy to follow up and understand even the difficult topics. I have a request to you that you can make a series on how to pass general chemistry 2. Because you are the reason I passed gen chem 1 and really want your help for gen chem 2. So please consider my request.
Hello melissa I just finished gen chem 2. I bought ur subscription to chemmunity. I want to get ahead of my class. In what order do I start studying the videos.
Start with the videos in the general chemistry section, www.chemmunity.com/categories/general-chemistry-review Feel free to email our team at hello@chemmunity.com and they will give you a list of videos to watch first.
it's confusing me ch3oh is a weak nucleophile so could be between sn1/e1 but vinyl carbocation will form and that is not stable so what will be the answer
None because the carbon is sp2 hybridized, so it’s more electronegative and can’t be easily turned into a carbocation (which eliminates Sn1 and E1). Backside attack is sterically hindered bc so no Sn2. And the double bond cannot rotate which eliminates E2. Also you could just remember the rule that vinyl (which is what the problem is) and aryl halides cannot undergo any of the 4 reactions.

How do you know if something is neutral or a strong nucleophile?
They look like they r strong 😭
@@Typically-Vpls bye😭😭
A strong nucleophile has either a negative charge or sodium or potassium as an opposing ion
Or a lone pair, just calculate their number of lone pair
@@ilyessbouabid6395 thanks!!
Thanks so much for making my studies fun😊
I just wanted to hop on here and say thank you, with much help from your videos I was able to pass college chem with an A. ❤
Thank you so much Melissa😊

Just in time before my upcoming o chem exam!! Thank you!
Ladyyyyy Your videos evening helping Masters student ❤

Dang, this video is really good. Super helpful!
Thanks you so much for making me understand it 🙏
I need those key info flash cards!
What’s the answer to the very final difficulty level 2 problem?
Both SN1 and E1 rxn.....so you draw products for both rxns
@@Elvis._563Am I tripping or is that a vinyl bromide? You know, one that doesn’t do SN2, and doesn’t form the really unstable vinyl cation?
@@joshuamitchell5530 you tripping bro
@@Elvis._563 care to explain how this can form a carbocation for SN1 or E1?
it's confusing me
ch3oh is a weak nucleophile so could be between sn1/e1
but vinyl carbocation will form and that is not stable so what will be the answer
uhmm, how did you know it is a primary (1°) or secondary (2°)?😢
You need to see how many carbon are directly attached to the carbon with the leaving group
1>primary
2>secondary
3>tertiary
Hope i had found it earlier, it's too LATE NOW!!
i need answer for that last question
No reaction. SP2 carbons do not undergo substitution or elimination.
None because the carbon is sp2 hybridized, so it’s more electronegative and can’t be easily turned into a carbocation (which eliminates Sn1 and E1). Backside attack is sterically hindered bc so no Sn2. And the double bond cannot rotate which eliminates E2.
